Pollutant Identified As Mineral Spirits

February 28, 1990

LAKE ZURICH — The company that accidentally spilled a foreign substance into Lake Zurich sewers and a pond identified the material Tuesday as mineral spirits. R.A. Briggs & Co., a towel manufacturer located near the pond, said in a statement that ``the release is now contained`` and a recovery program under way has the approval of the U.S. Environmental Protection Agency. The statement said the mineral spirits are hazardous only because they are flammable, and fire is not a danger because the substance spilled into water.
